.TH "Netpbm subroutine library: pm_tmpfile_fd() function" 3 "31 December 2007" "netpbm documentation"

 
.SH NAME

pm_tmpfile_fd() - create a temporary unnamed file

.SH SYNOPSIS

.nf
#include <netpbm/pm.h>

FILE *
pm_tmpfile_fd(void);
.fi

.SH EXAMPLE
.PP
This simple example creates a temporary file, writes "hello
world" to it, then reads back and prints those contents.

.nf
#include <netpbm/pm.h>

int fd;

fd = pm_tmpfile();

write(fd, "hello world\en", 17);

lseek(fd, 0, SEEK_SET);

read(fd, buffer, sizeof(buffer));

fprintf(STDOUT, "temp file contains '%s'\en", buffer);

close(fd);

.fi

.SH DESCRIPTION
.PP
This library function is part of
.BR "Netpbm" (1)\c
\&.
.PP
\fBpm_tmpfile_fd()\fP is analogous to
.BR "\fBpm_tmpfile()\fP" (1)\c
\&.  The only difference is
that it opens the file as a low level file, as \fBopen()\fP would,
rather than as a stream, as \fBfopen()\fP would.
.PP
If you need to refer to the temporary file by name, use
\fBpm_make_tmpfile_fd()\fP instead.

.SH HISTORY
.PP
\fBpm_tmpfile()\fP was introduced in Netpbm 10.42 (March 2008).
